Title: Improvements in the manufacture of hose pipes
Inventor: HIRD DESMOND
IPC: B29C48/153
Filed: 1965-02-03
Abstract: 1,076,102. Extruding reinforced tubing. GEORGE ANGUS & CO. Ltd. Jan. 19, 1966 [Feb. 3, 1965], No. 4758/65. Heading B5A. [Also in Division F2] Tubing, particularly for use as hose pipe, is made by pulling through an extrusion head 24 a textile jacket 10, e.g. of polyalkylene terephthalate, and a reinforcing tube 13, e.g. of nylon, which latter moves with the jacket by frictional contact against the inner surface thereof, and forcing plastics material, e.g. P.V.C. or rubber, through the interstices of the jacket 10 and tube 13 to bond them together and to form a lining 12. The tube 13 may be a seamless woven or knitted tube or be formed by gumming at intervals, e.g. with rubber latex or rubber solution, the overlap (16), Fig. 3 (not shown), of a strip of cloth (14) folded round a former (15). The reinforced tubing is shown in detail in Figs. 1 and 2 (not reproduced) where the plastics or rubber forms a cover (11), intermediate lining (12A) and inner lining (12). Tube 13 may be introduced within jacket 10 as the latter is made on a circular loom, Fig. 4 (not shown), and the combination fed to the extrusion head from a reel (23), Fig. 5 (not shown), via extension (31) of mandrel (27) and clamps (32), (33) which act to corrugate jacket 10 and thereby form a store (23A) and a reserve supply (23B) of this material. Alternatively, tube 13, Fig. 7, may be stored in corrugated form within a plastics sleeve 34, from which it is led into contact with jacket 10, with the latter still being stored between clamps (32), (33), Fig. 6 (not shown) as before. After leaving head (24) the reinforced tube may pass through a cooling bath (25) and be received on a take-up spool (26).

Title: Improvements relating to metal working presses
IPC: B21J15/22
Filed: 1932-02-18
Abstract: 388,202. Presses. GLASNER, R. W. and RODE, E. J., 6500, West 65th Street, Chicago, U.S.A. Feb. 18, 1932, No. 4788. [Class 83 (iv).] Riveting.-A metal-working press having fluid-pressure cushioning means fed from a reservoir contained within the machine is provided with means for swinging the lower platen 30 with the cushioning means, out of position with respect to the reciprocating die 12. The die 12 is mounted on a ram which is reciprocated on a slideway 13 by a crank arm on a shaft driven by gearing 20. The cushioning-device comprises a cylinder 21 which is adjustably secured to a vertical part 25 of the machine framing by means of T-headed bolts 22 slidable in vertical slots 24. A piston 28 working in this cylinder is secured to the lower platen which supports the lower die 31. A reservoir 32, supplied from a pipe 37, has an outlet pipe 33 leading to vertical member having a tubular portion 35 discharging into the cylinder through a passage 36 and valve 41. The valve is held on its seating by the pressure in a cylinder 42 having a stationary piston 44 and supplied by a pressure line 46. Fluid may also pass from the passage 36 to the cylinder through a valve 51 which is normally seated by a spring 52. When the upper die descends and engages with the work the rise of pressure in the cylinder 21 opens the valve 41 against the predetermined resistance of the cylinder 42 and fluid can then flow through the passage 36 and pipe 33 back to the reservoir, thus providing an adjustable cushioning effect. When the pressure is relieved by the raising of the upper die the valve 41 is seated and the valve 51 opened by the reservoir pressure so that fluid flows into the cylinder and raises the lower die to its normal position, which may be determined by the engagement of the heads 68 of bolts 66 secured to the lower platen, with ears 67 on the cylinder block. The cylinder block carries arms 54, 55, connected to a tubular member 56 slidable and rotatable on the member 34. Stuffing boxes are provided at 57, 58 and the tubular part 35 is bored so that it communicates with an annular recess 59 in the member 56. This construction enables the cylinder 21 to be vertically adjusted while keeping the passage 36 in constant communication with the reservoir. This adjustment is effected by a screw 61 carrying a collar 63 engageable with the cylinder block and a pin 65 engageable with an arcuate slot in the base of the cylinder. The securing bolts 22 are slacked off during this adjustment. In order to swing the lower platen with its cushioning means about the axis of the member 34 the nuts 27 are screwed off and the cylinder block lowered by the screw 61 until the gland 58 rests on a collar 53 at the lower end of the member 34. The pipe 46 is disconnected and the cylinder and platen can then be swung aside into the position shown in Fig. 5.

Title: Improvements in the preparation of nutrient solutions for the production of citric acid by fermentation
IPC: C12P7/48
Filed: 1940-03-14
Abstract: In a process of preparing citric acid by quiet surface fermentation from sugar-containing nutrient solutions, e.g. molasses, with a mould of the usual type, the content of surface-active substances in the solution is reduced to a predetermined optimum before inoculation with the mould.  The optimum is determined by series experiments. The reduction may be effected by (1) injecting air and removing the foam; (2) the addition and separation of absorbent substances, e.g. charcoal, activated carbon, bleaching earths, silica, or alumina gel; or (3) precipitation of insoluble substances in the solution and separation thereof, e.g. barium sulphate, insoluble sulphides, hydroxides, carbonates, or other insoluble compounds of the heavy metals or alkaline earths.  Examples of the preparation of citric acid from molasses by methods (1), (2) using activated carbon, and (3) precipitating zinc sulphide, are given, and also a comparative example without such methods.  Alternatives to molasses are pressed juices and mashes containing saccharified starch.

IPC: B23P15/30
Filed: 1965-02-04
Abstract: 1,088,497. Cutting tools; making diamond cutting tools. ALLM€NNA SVENSKA ELEKTRISKA A.B. Feb. 4, 1965 [Feb. 6, 1964], No. 4828/65. Headings B3A, B3B and B3C. A cutting insert for rotary rock drill, shell drills, cutters etc. has cutting edges 11-14 etc. and comprises a matrix 15 of metal alloy, hard metal etc., with diamond grains 16 impressed therein. The insert is produced by coating a high speed steel plate with adhesive, placing diamond grains on the plate, placing a second plate on the diamonds and pressing them together in a press so that some of the grains are pressed into each plate so that, when separated 21% remain on the upper plate, 25% on the lower and the remainder are washed away. The plate surface is covered with a nitrate binder for the purpose of improving the fastening of the diamond grains. In a modification, the grains are impressed, sprayed or blasted into a matrix of unhardened material at a high temperature, and after the grains have set, the matrix is hardened rapidly. The pressing conditions can be varied both as regards pressure exerted on the matrix at the beginning of the operation by employing hydrostatic pressure, and, as regards pressing speed, for example increasing the pressure rapidly by employing explosives.

Title: Improvements in clarifiers
Inventor: BOOTH ROBERT B
IPC: B03D1/16
Filed: 1944-03-15
Abstract: A unit for continuously removing contaminants from lubricating coolants comprises a vessel 1, Fig. 1, with a section 1a receiving the coolant and collecting relatively heavy particles of contaminant, the coolant flowing from this section to a flotation section 1b containing means for agitating and aerating the coolant to form a froth which is discharged together with lighter particles through an outlet 29, while the purified coolant passes to a receptacle <PICT:0619214/III/1> <PICT:0619214/III/2> <PICT:0619214/III/3> <PICT:0619214/III/4> <PICT:0619214/III/5> 33.  The froth is formed by a rotary motor-driven device 12 which aerates the liquid with air drawn through a casing 20.  The froth is removed by a rotary skimmer 28.  A byepass pipe 38, a control valve 36, and a check valve 39 are provided to maintain a substantially steady flow of liquid through the clarifier, part of the clarified liquid being re-circulated if the flow of incoming liquid falls below the desired rate.  In a modification shown in Figs. 2 and 3, the clarifier comprises three sections 41, 42, 43. The coolant enters the section 41 from which settled solids are removed by rakes 47 on endless chains 48 and delivered to a portable tank 60.  The coolant flows from the section 41 by way of a slot 59, a baffle 61 and an opening 62 into section 42 which is provided with a rotary froth-flotation device 65.  The froth is removed by a skimmer 68 and the clear liquid flows through an opening 76 into the section 43 from which it is pumped through pipe 78.  In a further modification three cylindrical members are arranged coaxially, the heavier solids being collected in the outer chamber, the froth in the inner chamber, and clarified liquid in the intermediate chamber.  In the construction shown in Fig. 8 the froth is formed by a blower supplying compressed air through a distributor 155 provided with a canvas sheet 157.  The distributor divides a casing 150 into two sections, the lower section collecting heavier solids 152 from coolant supplied through pipe 151, and the upper section containing the froth which is removed by a skimmer 158. Clear liquid flows through outlet 162.  Means may be provided, as shown in Fig. 10, for removing automatically the solids in the settling chamber 200.  The chamber has a conical base with an opening fitted with a plug 202 which is connected to a float 207.  When sufficient solids accumulate in the chamber the float 206 rises and through lever mechanism withdraws the plug 202 from its seating allowing the solids to escape.  Specification 615,705 is referred to.

Title: Process for deep fat frying
IPC: A23L5/10
Filed: 1964-02-05
Abstract: 1,059,921. Deep fat frying. GENERAL MILLS Inc. Feb. 5, 1964 [Feb. 14, 1963], No. 4925/64. Heading A4D. In a deep fat frying process, the rate at which a food product is conveyed through the apparatus is adjusted in accordance with the temperature of the fat and the capacity of a fat circulating system so that sufficient fat is entrained in the cooked product for the quantity of fresh fat, added to make up this loss, to prevent thermal decomposition and oxidation products from accumulating in the circulating fat. The fresh fat is preferably added at an hourly rate equal to a third or a quarter of the total volume of circulating fat. Fat circulating system: the flow of fat, produced by pump 140, is controlled by an electrically operated valve responsive to a flowmeter 144 by means of a servomechanism. The fat is returned via pump 140 and flowmeter 144 to a heating tank 137 in which it is heated by direct contact with a heating coil. The heated fat flows through pipe 136 to frying tank 21 and through pipe 139 to filter 141 and pump 140. Fresh fat is supplied from tank 152 through a solenoid operated valve which is controlled by level sensing contacts 156 and 157 in a surge tank 151 (Fig. 3, not shown). Food conveyer arrangements: food containing buckets 46 are pivotally mounted on the ends of spider arms 29 which are rotatable, by means of shaft 32 to convey the buckets through the fat. The buckets 46 are charged as they pass beneath a shoot 109, into which equal portions of potato chips or dough pellets are delivered by rotatable drum 111, having a partitioned metering chamber 121 with a discharge opening 122. After it has been conveyed through the hot fat, an actuating lug on the bucket is displaced by stationary guides 64 to open the bottom gates of the bucket and allow the product to fall into shoot 108. Simultaneously, the bucket is prepared for a fresh charge by opening the lid and applying an air blast from nozzle 91 to detach any matter sticking to the walls. The lid stays open to allow charging, after the actuating lug has been removed from guide 64, and the gates have sprung back to close the bottom of the bucket.

Filed: 1960-02-15
Abstract: 949, 216. Electric correspondence control systems. ASHWELL & NESBIT Ltd. Jan. 25, 1961 [Feb. 15,1960], No. 5266/60. Heading G1N. [Also in Division F4] A control arrangement for a mechanical stoker in a hot water boiler comprises means for effecting periodic operation of the fuel feed drive in accordance with variations in a control temperature. The control arrangement comprises a micro switch 1 with an arm 2 pivotally connected to a vertically slidable member 4, which can be adjusted by a screw 7 against a spring 6. The switch contacts (not shown) are operated by a leaf spring 9 held against the switch housing by a spring 12 and resting on an eccentric motor-driven disc 10, the contacts being closed when the arm 2 is free. The control rod is moved up or down in a casing 17, disposed in the boiler, by the expansion or contraction of bellows 16 against a spring 14 due to the contraction or expansion of a readily expansible liquid surrounding the bellows. As the temperature rises after a fuel feed motor has been started, the control rod rises, raising the switch arm 2 and breaking the switch contacts during part of each revolution of disc 10,thus causing intermittent fuel feed to the grate. In another embodiment, Fig. 2 (not shown), applied to a steam boiler, the control rod is. actuated directly by the steam pressure, a damping effect being provided by a spring acting against an adjustable stop plate as the control rod rises and opens the bellows which are now inside the main chamber 6a. The aforementioned control arrangements may be applied to an underfeed stoker, Figs. 3, 4 (not shown) which has one motor for driving the fuel feed screw and another for a fan supplying combustion air above and below the grate through a controllable proportioning damper. The primary air supplied below the grate is controlled by another damper actuated by a governor device driven from the fuel feed motor. Another embodiment, Fig. 5, comprises the micro switch 35, arm 36 and leaf spring 51 as before, but the arm is pivoted at a point 37, and rests on an adjustable stop 41 on a partly threaded rod 42 connected to bellows 43 separated from the arm by a spring 44. The bellows, a connecting capillary tube and a phial 55 located in the water boiler, are all filled with a readily expansible fluid, which when heated forces the bellows open, causing the arm 36 to move down against the damping action of a spring 46, whose resistance can be altered by moving the handwheel 49, lockable by a pin 50. In a steam boiler, the steam can be fed direct into the bellows, the phial and capillary tube being omitted.
